Not Able to use the keyboard on Android 14

Question

Android application type

Xamarin.Forms application Xamarin.Android application

Affected platform version

Android 14 Emulator (pixel 7 pro)

 

Unaffected platforms tested

Android 13 emulator(pixel 5), Android 9 emulator(pixel 2), Android 14 Device (Samsung s21fe), Android 13 device (S20fe).

 

Description: When using the Edit text on the alert dialog box, opening the alert dialog box 2nd time makes the built-in keyboard unusable

Steps to Reproduce:

1. Open the application https://www.syncfusion.com/downloads/support/directtrac/general/ze/AlertDialogIssue-1286220461
2. Press open dialog
3. Enter any text in Edit text and press OK
4. Now the keyboard is visible but we were unable to interact with the keyboard

We have created a custom alert dialog with the following codes

CustomAlertDialog.xml

We are invoking the custom alert dialog on the main activity using the following code

customAlertDialog.ShowPasswordInputDialog();

Hello,

Thanks for your feedback.

After testing, this problem only occurs on pixel 7 pro API level 34. The application runs as expected on the Pixel 5 emulator at the same API level.

Therefore, this should be more of a development tool issue.

Q&A is not a bug reporting or tracking system. If you think you've found a bug in Visual Studio please report it as described in Report a problem with the Visual Studio product or installer . We will clear details to be able to reproduce and troubleshoot the problem. When you post it, please include version numbers, exact repro steps, and the difference between the expected behaviour and actual behaviour.

Best Regards,

Alec Liu.
